Title: Production of styrene type polymers
IPC: C08F12/00
Filed: 1965-07-23
Abstract: A monovinyl aromatic hydrocarbon and/or its ar-halo derivative is polymerized by heating and increasing the temperature towards the end of the polymerization so that the last part only of the polymerization is at 180-220 DEG  C., at least the last part of the polymerization is effected in the presence of a catalyst which is an organoperoxysilane, other than t-butylperoxytrimethyl silane, having a half-life of 220-30,000 hours in benzene at 100 DEG  C.  The monomer may be styrene p-chlorostyrene, or o-, m- and p-methylstyrene with optionally a -methylstyrene, methyl methacrylate or acrylonitrile, and may contain a dissolved rubbery conjugated 1,3-diene polymer, e.g. a butadienestyrene copolymer. The silane may be a di- or tri-(t-butylperoxy) di- or mono-methyl silane, tetra (t-butylperoxy) silane, di (t-butylperoxy) methylphenylsilane or tri (t - butylperoxy) phenyl silane.  The monomers and catalyst may be heated at 75-125 DEG  C. until 15-45% conversion to polymer is obtained and the temperature is then raised to 180-200 DEG  C. over a period of 3-7 hours and maintained for 1/2 -5 hours.  The catalyst may also comprise hydrogen peroxide and di-t-butyl peroxide.  In comparative examples styrene is polymerized by heat alone and using di-t-butyl peroxide alone.

Abstract: 1,044,479. Amplitude modulation; valve amplifying circuits. CONTINENTAL ELECTRONICS MANUFACTURING CO. Aug. 4, 1964 [March 25, 1964], No. 31613/64. Headings H3R and H3W. In a Doherty-type power amplifier, modulation is applied to the screen grids of the carrier and peak modulation tetrodes T 1 , T 2 , carrier being applied directly to the peak tube control grid and through a 90-degree phase advance network 18 to the carrier tube control grid, the carrier tube output being connected to the peak output through an impedance inverting 90 degrees phase lag network 30, both outputs feeding an antenna. Both tubes are biased on their R.F. input control grids beyond cut-off to act as Class C stages but the screen grid of peak tube T 2  is at approximately earth potential so that only positive modulation half cycles cause it to conduct, while for carrier tube T only negative modulation half cycles reduce its carrier output, being otherwise saturated. Tubes T3, T4, T5, respectively a phase splitter, a cathode follower and an amplifier, and the two latter being biased to near cut-off, permit only positive modulation (D) and negative modulation voltages (E) to be applied to the peak and carrier tubes T 2 , T 1 , respectively, and therefore provide a system with class B efficiency without a modulation transformer.

IPC: H04N5/365
Filed: 1970-06-30
Abstract: 1302078 Infra-red television PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 30 June 1970 [2 July 1969] 31705/70 Heading H4F In an infra-red Vidicon television camera, comprising a detector 21 which, when illuminated with ultra-violet light from source 24 converts infra-red light 18 from object 17 to visible light 22 incident on the vidicon target 11 it is found that an output is produced by the camera even when an infra-red object is absent. This output is called spacial noise and the invention seeks to remove same. The target plate is connected to the cathode, by load resistor 15-positive (+45v), source of bias potential 16- earth- and load resistor 13. A switch 26 connects the load resistor 15 to output 27 or, via amplifier 14, to load resistor 13. Assuming that inner (free) surface of the photoconductive layer on the target has been charged to the electron beam to earth potential, the cycle of operation is as follows: (a) Light 24 is switched on, but a shutter 19 closes off the object 17 such that the only light emitted, detector 21 and causing a charge change on target 11, is that due to spatial noise. The target plate is held to + 45 volts so that the spatial noise increase the conductivity of the photoconduotive layer and pulls the potential of the inner surface towards that of the plate and so above earth by (+V noise), (b) Light 24 is switched off and the electron beam is switched on. The beam starts to pull the inner surface negative and this results as a current flowing in load 15 and the voltage applied to amplifier 14 becomes proportional to the spatial noise. This is connected by the amplifier and load 13 to a movement of the cathode potential to below earth by the voltage (-V noise). The electron beam transfers this negative voltage to the target inner surface such that it goes from (+V noise) to (-V noise), (c) Light 24 is switched on, the shutter 19 is removed to allow the object infra-red to fall on the detector, and the beam is switched off. The light now emitted by the detector is now due to the object plus spatial noise. The inner surface of the target now moves (V object +V noise) plus the (-V noise) already present, i.e. to (V object). (d) Light 24 is switched off, shutter 19 is pulled down, the electron beam is switched on, and switch 26 connects the output voltage on load 15 to terminal 27. As in step (b) the electron beam pulls the target inner surface towards the cathode potential (now earth) and the resultant current in load 15 gives the required output at terminal 27.
